Application June 4, 1938, Serial No. 211,897

12 Claims.

This invention relates to a fan traveler, and it is an object of the invention to provide a device of this kind adapted to be mounted for rotation upon a bobbin spindle of a ring twister, said fan traveler being in driven connection with the ring traveler through the instrumentality of the thread running from the delivery rolls of the twister to the bobbin.

It is also an object of the invention to provide a fan traveler which, when in operation, broadcasts a draft of air which will provide an effective medium to blow off from the adjacent portions of the twister all lint and other particles which would otherwise settle'thereon and also to keep slugs from twisting into the yarn.

An additional object of the invention is to provide a fan traveler which, when in operation, is so positioned to create an air blast to keep the lubricant applied to the traveler ring sufficiently cool so that the same will not run off the ring with the resultant liability of the ring traveler burning and the yarn passing through the traveler coming down.

Another object of the invention is to provide a 'fan traveler which provides an effective means to stretch the yarn While it is being twisted and wherein a selective variation of the stretching may be readily obtained.

Furthermore, it is an object of the invention to provide a fan traveler which, when in operation, provides means to aid in drying the yarn during a Wet twist and with the further object of avoiding the necessity of employing separators on the twister as is now the custom.

It is also a purpose of the invention to provide a fan traveler so constructed and mounted as to be equally efficient in connection with any ring twister; with any kind of yarn; wet or dry twist; or right and left twists.

One of the objections in connection withthe present types of traveler ring twisters is that the yarn as it passes to the traveler contacts with the upper flange of the bobbin with resultant injury to the yarn and which is of material disadvantage particularly in connection with fine work. It is an object of the invention to provide a fan traveler which obviates this disadvantage.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved fan traveler whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of our invention will hereinafter be definitely claimed.

In order that our invention may be the better understood, we will now proceed to describe the constructed in accordance with an embodiment of our invention and in applied position;

Figure 2 is a view in top plan of the fan traveler as herein disclosed unapplied.

In the accompanying drawing is illustrated only a single assembly for one of our fan travelers. It

is to be understood that one of our improved devices is to be employed in connection with each of the bobbin spindles I and that each of said spindles is to be rotated at a required speed through the medium of any of the well known mechanisms now in use; 7

As disclosed in Figure 1 of the drawing, the spindle I, as is well known, passes axially through a traveler ring 2 carried by the ring rail 3 and which rail is caused to rise up and down at predetermined speed with respect to the spindle. The mechanism for effecting this movement of the ring rail forms no part of the present invention. Coacting with the ring 2 in a well known manner is the traveler 4 through which is directed the yarn thread 5 which leadsfrom the conventional delivery rolls of a ring twister to the bobbin 6 mounted upon the spindle I.

The upper end portion of the spindle I is provided axially thereof with a socket 1. The upper portion of this socket I is enlarged, as at 8, to provide a cup for holding grease or other desired lubricant.

Rigidly engaged within the socket "I is the lower end portion of an elongated pin 9. This mounting of the pin 9- upon the spindle I is preferably accomplished by forcing the power portion of the pin 9 into the socket I although, of course, any other means may be employed to effect the desired rigid coupling.

In the accompanying drawing, the pin 9 is shown as being initially separate from the spindle I. This arrangement is of especial importance and advantage when it is desired to apply our improved fan traveler to a spindle already in use as it is only necessary to bore into the upper end portion of such spindle the proper socket I. It is to be stated, however, that in a new assembly the pin 9 and the spindle I may be integrally connected. This integral form, however, is believed to be nothing but a mechanical equivalent of what is shown in the accompanying drawing.

The fan traveler F comprises in the present embodiment of our invention an elongated and relatively narrow body I0 of light material, preferably hard wood. One end portion of the body I0 closely adjacent to a side thereof has disposed therethrougha guide eye II having associated therewith an entrance slot I2 open at the adjacent side of the body I. This guide eye II is provided Witha lining l4, preferably porcelain.

At its longitudinal and transverse centers the body In is provided therethrough with an opening 15 which as is illustrated in Figure 1, is of a diameter slightly in excess of the diameter of the pin 9. tinuation of an opening [6 disposed through the axial center of a weight member ll, preferably of brass. This member I! is of a width the same as the width of the body Ill and is of a material length, such length however being determined by the necessities of practice.

The opening l6 through the weight member I! is such as to snugly surround the pin 9 yet permitting the pin 9 and (the weight member to be substantially free of frictional contact. It is of importance to have the opening l5 of a greater. diameter than the. opening I6 so that the tendency of the pin 9 during its rotation to rotatethe fan traveler is, further reduced. ,It is, therefore, to be particularly understood that the pin 9 in fact only serves as a means for maintaining the body 10 together with the weight member, ll in appliedposition upon the top of the spindle l and that the relative diameters of the pin 9 and the opening l6 are such to eliminate as much as may be mechanically possible the tendency of the fan traveler to be rotated by the revolving pin 9. N This is of vital importance. as the rotation of the fan traveler is effected to the fullest possible degree through the medium of the yarn thread 5 which is disposed through the eye H of the body Ill. This rotation of the body Ill and the weight member l1 occurs as the traveler 4 traverses the ring 2 as the yarn thread winds upon the bobbin.

The weight member I! as herein disclosed is held to the under surface of the body ID by the screw members l8 although, of course, other means may be employed for thispurpose.

The body 10 as herein disclosed is provided in its extremitiesand at opposite sides thereof with the elongated notches l9. Each of these notches I9 is open along a side of the body Ill and. has its inner end wall 20 substantially at right angles to the longitudinal axis of the body Ill. The base wall 2| of the notch I9 is disposed inwardly on a predetermined angle. Y

Suitably secured along the inclined base wall 2| and extending above and below the body It) is a plate 22 which is continued at its outer extremity to extend across the adjacent end of the body ID. This plate 22 provides upper and lower fan blades 23 and the particular formation of these blades 23, as herein disclosed, assures the creation of effective air blasts as the body Ill rotates. The area of the fan blades 23 determine the amount of resistance offered to the body l0 in its rotation to determine the approximate extent of stretching imposed upon the yarn. It is to be stated at this time that we do not wish to be understood as limiting ourselves to the formation or design of the blades 23 as illustrated in the accompanying drawing as the same results can be obtained with blades of other formations, it only being essential that such fan blades be carried by the opposite end portions of the body I0.

The assembly of the body I0 and the weight member I1 is such as to assure a substantially perfect balance when the fan traveler is in applied position upon the pin 9 so that the fan traveler may be effectively rotated under the This opening I5 constitutes a conaction of the yarn thread 5 as hereinbefore mentioned.

When the yarn thread 5 is disposed through the guide eye H a maximum stretching action is imposed upon the thread. When, however, it is desired to reduce such stretching action the thread 5 is disposed through a supplemental guide eye 24 selectively positioned upon the body In inwardly of the guide eye I I. It is to be stated that the closer this supplemental guide eye 24 is positioned to the axial center of the body H) the lesser will be the stretching action.

It is of importance and advantage to interpose between the top or upper end of the spindle I and the applied fan traveler a spacing and bearing sleeve 25. This sleeve 25, as herein disclosed, is idle upon the pin 9 and the upper portion a of its bore 26 is enlarged to provide the reduced surface 21 for contact with the under flat face of the weight member ll so that the sleeve 25 has the least tendency to rotate the fan traveler.

This sleeve 25 also prevents the bottom of the fan traveler I I from wearing spindle l or, in other words, whatever wear occurs will be on the sleeve 25 and not the spindle I. The enlarged portion a of the bore 26 of the sleeve 25 also provides a grease cup between the assembled sleeve 25 and fan traveler ll. The opposite or lower end of the sleeve 25 also has its bore 26 enlarged to provide a grease cup 28 which cooperates with the grease cup 8 hereinbefore referred to.

This sleeve 25 serves to space the fan traveler I! from the top or upper end of the spindle I so that at no time will the fan traveler I1 and the upper portion of the bobbin 6 come into contact. It is also to be noted that the body I9, and particularly the portion carrying the eye member H, is positioned beyond the periphery of the top flange 29 of the applied bobbin 6 so that the yarn thread as it passes from the fan traveler I! to the traveler 4 will not contact with any portion of the bobbin.

While it has hereinbefore been set forth that g.

the fan blades 23 operate to impose stretch on the yarn thread, it is to be further stated that these blades serve to broadcast an air blast of considerable power and which blast is of particular advantage in keeping cool lubricant which has been applied to the ring 2 so that such lubricant will not melt and run down and thus allow the traveler 4 to burn and therefore bind with the further disadvantage of the yarn thread coming down. Furthermore, this air blast provides an effective means for blowing off lint and other particles which may have a tendency to settle on the adjacent portions of the twister itself and to keep slugs and any other foreign matter from twisting into the yarn. This air blast is also effective as an aid for drying when twisting wet yarn. Furthermore, as a result of this air blast it is not necessary to use separators as is now the custom, and it is also believed to be apparent that our improved fan traveler can be employed to advantage on any twister; in connection with any kind of yarn; wet or dry twist; or right and left twists.

It is believed to be obvious that the length of the body I9 is such that in actual practice one fan traveler will in no way interfere or obstruct the operation of the fan travelers mounted upon adjacent spindles.

While the body It] is herein disclosed as being elongated, it is believed to be obvious that it could be of a disk like form or other configuration without departing from the principles of the invention as herein disclosed.

From the foregoing description it is thought to be obvious that a fan traveler constructed in accordance with our invention is particularly Well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that our invention is susceptible of some change and modification Without departing from the principles and spirit thereof and for this reason We do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice except as hereinafter claimed.
